' BENJAMIN Nnwlvzamor NEW YORK, N. Y.

SMOKE-HELMET.

, To all whom it'may concern:

Be it known that I, BENJAMIN NE MA a citizen ofthe United States residing at New York, in the-county ofNew-York and State of New York, have invented certain new and useful Improvements in Smoke- Helmets; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.- i

This invention relates to new and useful improvements in smoke helmets "or respirators for firemen, mechanics, laborers, and all persons whose work is of such anature that they are constantly exposed to smoke, dust or deleterious gases.

The principal object of this invention contemplates the provision of a smoke helmet which maybe readily positioned over the face of the wearer and which carries means for preventing all smoke and gas from entering the helmet.-

A further object of this inventionis to construct the helmet'in [such manner that by merely placing it on the wearers face, the various parts of the device will act to effect za hermetic sealing of the edges of the helmet against the adjacent 'portioniof the wearers face and head.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

WVith reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reducedto practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is a front elevation of the helmet. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a rear elevation of the helmet disclosing the arrangement of the interior members; and Fig. i is a section on the line 4-4 of Fig. 2. illustrating in detail the sealing flap carried by the face of the helmet.

Proceeding now to the description of the drawings, the helmet includes a face ring 1 formed of wire or other similar and suitable material and shaped to approximately conform to the contour of the human face. Carried on the front edge of the ring 1 and "Specification of Letters Patent. 'P tented Mar. 28,1916. Application filed. Apri1'29, 1913. Serial No. 764,461. r

approximatelymid-way the length thereof are the spaced semi-circular ribs 2 and 3, held in rigid fixed relation toeach other by vertical stays 1, 5 and 6. The members 3, 4, 5- and 6 arepreferably wrapped with a cloth or fabric of any suitable. nature for v the obvious purpose of protecting the wearers' face. Connected at their upper terminals to the stay 5 and at their lower termi- -,nals to the lower portions of the sides of the ring 1, are a pair of arcuate stays 7 and 8. A similar set of arcuate stays 9, .10

and 11, respectively connect the members .4, 5 and 6 to a central point at the upper curved portion of the ring 1, as at 12. An eyelet 13 is formed integral with the members 9 and 11 to form a convenient means 7 for hanging the helmet on the wall within, easy reach of the user of the device. A sub-' stantially semi-circular stay '14 is carried by the; lower cross member 15 of the ring 1, and extends forwardly therefrom, being of smaller size than themembers' 2 and 3.

Connecting the member 5 with the terminals of the crossbar 15 are a pair. of arcuate stays 16 and 17 which may be wrapped to the members 14 at the inner terminals thereof by a suitable cloth or ,fabricstrip-IS.

, i The entire structure above disclosed, in-

cluding the face ring and the stays, 1s covered with any suitable cloth material indicated by the letter A. This cloth is pro vided with an opening corresponding in size with the stays indicated by the numerals 2, 3, 4: and 6. Mounted between the stays and the cloth covering is an isinglass strip 19 provided for the obvious purpose other suitable material arranged between.

the two members 16 and 17. The tube 20 .may be removably attached to a fix ed'sleeve 21, the inner terminal of which is provided with a funnel 22 for the obvious purpose of dispersing the incoming air. The tube 20 is of sufficient length to reach the floor when the helmet is in assembled position on.

the wearers face. and is provided at its lower terminal with a funnel mouth 22'. In this connection it is to be observed that if the helmet is employed by a householder who is confined in a burning house, that he Copies of thispatent may be obtained for may pass the tube-out of the window, this gettmg an adequate. amount of. freshiair to prevent his suffocating by the'inhalation of smoke, and that the wearer'may, at the same time, employ the tube 20 and funnel.

22 as amegaphone in his cries for help. It is also to is of sufficient length to reach the floor or surface onwhich the wearer of the helmet.

is standing,

that a supplyof comparatively fresh air will be thus-assured to the user of this device, for-it is a well known factthat even in burning buildings filled. with smoke, a fresh current of air will be found for a-small space above the floors,- of each room.

Asa means for assuringasealingzof the fa'ce'ring on thecheeks and other portions of the wearers face and head, there is pro .vided a flexible flange 23 formed of rubber, or any other suitable material which? will not have. a tendency to chafe or incon venience the wearer. As illustrated in Fig.

fabric,

4-, this flange is fixed to. the ring and extends inwardlv, being. directed at an angle to the plane of the ring.

In reduction to practice, I have found that th'e'form of my invention, illustrated in the drawings andrreferred to in the above description. as the preferred embodiment, is the most eiiicient and practical; yet-realizins. that the conditions concurrent with the adoption of my device will necessarily vary,

1 idesire to emphasize the fact that various minor changes 1n details of construction,

be observed that since thetube' proportion'and arrangement of parts may be resortedto, when required, without sacrificirig any of the .advantagesof my invention, ,as defined in the appended claims What is claimed is:
